As one of AT&T's top services and integration partners, Breakthrough Technology Group (BTG) has been leveraging is legacy expertise in enterprise networks into private cloud architecture, configuration and management solutions.

Now, it is expanding its reach in mobile device management through the acquisition of CelPro, a New York-based mobile systems integrator that has deployed mobile management solutions for more than 150,000 devices.

Terms of the deal weren't announced.

"This acquisition positions BTG not only as the one-stop shop where organizations of all sizes can solve their mobility and wireless problems, but also as the most complete IT and telecom solutions provider," said Jeff Kaplan, CEO and founder of the company, in a statement. "Mobility is at the heart of the technical evolution, as mobile app development and deployment affects every corner of operations as part of an ongoing quest to improve productivity."

CelPro will officially become known as BTG Mobility. It will provide services such as mobile platform monitoring and support for Apple iOS, Android, RIM BlackBerry and the various Windows mobile platform flavors. The group will also focus on mobile device management (as it has historically done), including strategies for companies that are introducing or grappling with BYOD strategies. It will also offer mobile application development services, an increasingly common consideration for businesses that have high-profile consumer brands.

BTG, based in Morganville, N.J., has been AT&T's top revenue-generating solution provider partner for the past three years.
